Geodesic Octahedron (or Hexahedron)

Another model I started making nearly three years ago was a paper geodesic octahedron.

Or, if you please, a geodesic hexahedron (cube).

Geodesic Hexahedron

It's a dual model because the model is made up of forty-eight triangles and you can look at it as eight faces of six triangles (octahedron), or six faces of eight triangles (hexahedron/cube).

This was another pretty simple model to make, with the net taken from Vince Matsko.  You'll need to print eight pages of that net, but there's a catch: you need to make half of the triangles "left-handed" and half of the triangles "right-handed" - folding the strips "inwards" for half, and "outwards" for the other half.  If you want to make a two-colour model, as I have above, you'll need to make all the triangles of one colour left-handed, and all the triangles of the other colour right-handed.  Again, I stuffed this up when I was making it, and so I've had to make two models - oops!
